When your Kindle device simply refuses to connect to the WiFi network and allow you to download apps or browse the Internet. While this can be frustrating, you are not alone, and there are a few solutions available.
Solution: This may sound obvious, but ensure that you have not switched to Airplane Mode. If that is not the case, then you can try rebooting your device (press Power button for 40 seconds so that it powers off and then on again). Additionally, you should also download the Wi-fi Analyzer and similar apps from Amazon Kindle Helpline phone number @ +1-877-930-1494 to better diagnose all Wi-Fi related problems. It may be that the problem lies not with your Kindle device but the router; it can’t hurt to check it as well.
